- and others
This paper presents two case studies that detail the benefits of a condition - monitoring system installed on a 400-kV air-blast PK type circuit breaker and an 800-kV SFA SF{sub 6} double-pressure circuit breaker. On the air-blast breaker, the monitoring system detected a mechanical malfunction that was judged sufficiently severe to reduce the breaking capability of the breaker, and possibly cause a catastrophic explosion. In the case of the SFA breaker, a deficiency in the high-pressure tank insulation was found during the past winter when the outdoor temperature reached -25{degrees}F. The paper also briefly discusses the upgrading of the monitoring system since the last EPRI conference and its adaptation to other strategic equipment.
